Senior chemistry laboratory technician / HES chemical engineer

In a demanding and diverse technical and analytical environment, you will contribute to high value-added activities, particularly around micropollutants, industrial compounds and complex matrices (air, water, soil, waste).

You will put your expertise at the service of analytical development, the evolution of technologies and the instrumental park.

• Be a technical referent for industrial and micropollutant analyses, mainly in air, water and soil matrices.
• Develop, validate and optimize analytical methods, notably by GC, LC, GC-MS, LC-MS and associated techniques.
• Guarantee the quality, reliability and relevance of analytical methods and results, in compliance with laboratory requirements and applicable standards (ISO 17025, ISO 9001, GLP).
• Contribute to the management of the analytical park (Asset Management) and investments (CAPEX), according to the needs and evolution of activities.
• Contribute to the organization and coordination of analytical activities according to priorities, available resources and client needs within the department.
• Participate in the evolution of analytical capacities and laboratory processes in order to support the objectives and strategic axes of the department and the mission of CIMO.

Contribute to the implementation, monitoring and continuous improvement of micropollutant and industrial sample analyses (air, water, soil), using notably gas or liquid chromatography and mass spectrometry (GC, LC, GC-MS, GC-MS/MS, LC-MS, LC-MS/MS). Contribute to organizing analyses according to priorities, workload and available resources, in collaboration with other team members. Provide technical support to laboratory technicians: methodological advice, problem solving and daily support. Ensure and participate in the maintenance of analytical equipment as well as the technical monitoring of instruments. Propose, develop, validate and optimize analytical methods according to the needs of the department and client expectations. Contribute to the management of the analytical park (Asset Management) and investment projects (CAPEX), from the definition of needs to commissioning and equipment monitoring. Contribute to technical documentation as well as the writing of analysis and activity reports. Ensure a role as a technical referent, ensuring the quality, reliability and compliance of methods and results with laboratory requirements and the ISO/IEC 17025 standard. Actively participate in the management of non-conformities and internal or external audits related to quality. Get involved in the continuous improvement processes of the laboratory, both on a technical and organizational level. Minimum: CFC as a chemistry laboratory technician (or equivalent in Switzerland or abroad). Asset: HES chemical engineer and/or higher education in analytical chemistry, environmental chemistry or analytical sciences. Minimum 7 years of experience in an analytical laboratory, ideally in the fields of environmental and industrial analytical chemistry. Confirmed mastery of GC, LC, GC-MS, LC-MS, GC-MS/MS and UPLC-MS/MS techniques. Experience in the development, validation and adaptation of analytical methods. Very good knowledge of micropollutants and their analysis in air, water and soil matrices. Experience in the maintenance and technical monitoring of analytical equipment. Good knowledge of quality requirements and ISO 9001, ISO 17025 and GLP standards. Experience in writing procedures and participating in quality audits. Ability to analyze complex situations and propose suitable technical solutions. Experience in the technical support of colleagues and/or projects, without necessarily having held a hierarchical position. Mastery of IT tools and technical laboratory software (Limpsophy); SAP constitutes an asset. Experience in investment projects for analytical equipment (CAPEX) and/or in the management of an instrumental park constitutes an asset. Sense of organization, reactivity and adaptability to changing priorities. Ability to work autonomously while collaborating effectively with the team. Service-oriented, transversal support to colleagues and good internal communication. Spirit of initiative and continuous improvement, with an economic and pragmatic approach to methods.
